Survival Shooter Q&A

Thank you very much Mr. Will.
I was having problem with Nav Mesh Generation, I hope I will find solution in the guide.
thanks

 

i can't be turning with mouse please help me !! (

Hello Midomady,

your code seems to be correct. Did you set

Code (CSharp):

1. PlayerRigidBody = GetComponent<Rigidbody>();

in your Awake() function?

Also note, that the easiest way to debug your application is to print your variables and find exactly where the problem is. Try using sample code bellow for your turning function. When you find anything odd in the console ('null' being printed etc.) just click on that line. The editor should open your MonoDevelop at the line where the print was done.

Hope that helps you a bit,
rePhat

Code (CSharp):

1.  
2.   void Turning() {
3.      Ray camRay = Camera.main.ScreenPointToRay(Input.mousePosition);
4.      Debug.Log("camRay "+camRay);
5.      RaycastHit floorHit;
6.    
7.      if(Physics.Raycast(camRay, out floorHit, camRayLength, floorMask)){
8.        Vector3 playerToMouse = floorHit.point - transform.position;
9.        playerToMouse.y = 0f;
10.        Debug.Log("playerToMouse "+playerToMouse);
11.      
12.        Quaternion newRotation = Quaternion.LookRotation(playerToMouse);
13.        Debug.Log("newRotation "+newRotation);
14.  
15.        PlayerRigidBody.MoveRotation(newRotation);
16.        Debug.Log("PlayerRigidBody "+PlayerRigidBody);
17.      }
18.      else
19.        Debug.Log("ray didnt hit");
20.    }
21.  

 

Hello,

I'm trying to solve this issue to no avail and I'm getting quite desperate. Since the Environment is being stored within the assets as a prefab (not a model), I'm not able to access Model tab in my inspector.

Any ideas?

 

@willgoldstone Well, I've downloaded it a week ago, how old is the new version? I'm using v5.1.1. Also thanks for your quick response

EDIT: I'm downloading new assets, thanks!

 

Thank you so much for this! It arrived just at the right time. Loving the learning journey.

I noticed a small mistake in the "04. CREATING ENEMY #1" Section of the PDF. The second paragraph indicates the time 01:20. It should be 11:20. It's obvious once you get to that part but for it could be confusing for some folks who are not paying enough attention.

Again, thanks for the help with this. Here's hoping to see new tutorials soon!

i'm sorry for asking too many questions but.... something weird happend after i finished chapter 6 and everything worked fine the backgroung and the scene setting... disappeared... sort of....


I am getting the same problem. Different from the other black scene issue. The background is black at the very start. Firing does provide lighting up the areas. So i guess it is a lightning problem, but appears at it should after you die once. So if i add lightning, i am over compensating after player respawn.

 

I had that same problem a couple of minutes ago. After some searching on the forums, found out that apparently there's a bug where the Editor fails to bake the lights after Application.Loadlevel. To fix it, go to Window > Lighting > Lightmaps Tab and uncheck "Auto" to avoid continuous baking and then press Build.

That worked for me!

 

The problem is everything is ok !!!!!!!!!!! look at this ((((

 

@midomady304 I'm seeing just two variables and its not obvious which are theese.. Its generally good to print the same text, like your variable name in order to avoid confusion. The most important one for this particular task is your RigidBody., and therefore I have to ask you again, did u set your reference in the Awake() function?

 

do you mean this !

Code (CSharp):

1.  
2. void Awake ()
3. {
4.  
5. floorMask = LayerMask.GetMask ("Floor");
6. anim = GetComponent <Animator> ();
7. playerRigidbody = GetComponent <Rigidbody> ();
8. }

 

Yes, exactly this. Can you upload your project somewhere, so I can take a closer look? It may be of help for other people having the same problem

 

i upload the project here
https://drive.google.com/file/d/0B-Ovmu9fEsURTXJyLVhZVFYyelU/view?usp=sharing

 

the problem is when i started make this project 1st time everything was ok !!!!!
now i tried and i have this problem (((((((

 

I understand this is the new thread.

I would like to point out a possible issue or bug in the C# script for "Creating Enemy #1" of the tutorial.

http://unity3d.com/learn/tutorials/projects/survival-shooter/enemy-one

This person's post from the old closed thread helped me get it working where the enemy just moved to the center of the level and stayed there moving and did not follow the player.

http://forum.unity3d.com/threads/survival-shooter-q-a.313934/page-2#post-2101162

So I also changed (Line 15) of that script from

Code (CSharp):

1. player = GameObject.FindGameObjectWithTag ("Player").transform;

to

Code (CSharp):

1. player = GameObject.Find ("Player").transform;

and it works, the enemy follows the player character

I also notice that the summary tooltip description in MonoDevelop-Unity for Find has a description of what it does,
"Finds a game object by name and returns it" but the FindGameObjectWithTag does not have a summary tooltip


I have not yet made a full game using Tags all the way through in code but this would be a problem. Perhaps I need to work more with Tags in code to see them working. If I encounter anymore of these issues I will let Unity know somehow.

 

EDIT: I have solved my problem with

Code (CSharp):

1. FindGameObjectWithTag ("Player")

I AM USING UNITY 5.1.1f1.

I WAS NOT USING THE CORRECT ASSET PACKAGE FOR UNITY 5.1 WHEN I CREATED THE PROJECT.

SO I HAVE CREATED A NEW PROJECT USING THE ASSET PACKAGE CALLED "Unity 5 Survival Shooter"

(THE PACKAGE I WAS USING BEFORE WAS CALLED "Survival Shooter")

Thank you for the help.

 

Please help me!! I'm blocked at lession 2 and the animation of walking don't working. Why? Sorry my bad English, but I'm Italian.

 

Can you give us any more detailed information? Can you tell us what you've used as your setup? Where is the project it's breaking?

 

Hi Guys,

In the new asset package I downloaded as above, there was no 'floor' layer in the drop down list ??


U_nitty.

 

any one can help me with my problem ! (

 

Thanks, that fixed a lot of the problems I was having (including only the gun moving during the animation)

 

@midomady304

PlayerRigidBody.MoveRotation(newRotation);

should be:

playerRigidbody.MoveRotation(newRotation); // Set players rotation to this new rotation

In your code you use PlayerRigidBody instead of playerRigidbody.

Lowercase 'b' needed ?
Lowercase 'p' needed ?

@peteorstrike
I fixed it already by creating a user layer 'Floor' and creating and applying a tag 'Floor' .
Thanks for the update - will download later

Hello, I am having an issue with the camera setup in chapter 3. I followed the video tutorial but when I press play, the bottom half the game preview screen is cut off and the map disappears and becomes grey. The top half is visible but when I move it becomes transparent and looks weird. I re watched the tutorials and looked at my script and it all seems to be the same so I am confused at the moment. I am also running on unity 5.0.1fl because that is what my school is currently at so that might be part of the issue but I am unsure. Any help would be appreciated as I am very eager to learn!

 

Hi, I completed the tutorial and everything works fine, except the scoring, everything is scoring twice, any ideas as where this bug may be?

Thanks

 

All my camera settings were correct except depth and clear flags, I changed them and the issue is still there, here is a screenshot

 

Hi!

I'm having a problem on phase 2, as the animations don't work as they should. When I run the game, the Idle animation is shown. Fine so far. But when I try to move, the animation Move is not shown. It seems that only when Idle animation finishes, the Move animation is called; and when I stop moving, I have to wait again for Idle to finish.

Also, if Idle animation finishes and I'm not moving, it gets stuck and no animation is shown.

It doesn't seem to be a scripting error, as I see how the "IsWalking" parameters is set to true while i'm moving.

How can I break the Idle animation for changing to the Move one?

 

I had a bit of debugging to do in the final phase of the project, and I've seen others with similar issues but no answer, so here's the way I fixed it.

My problem was the Game Over animation/text was never shown, although the game would restart itself. I found that, unlike the video, the Player Death animation was set to fire an event "RestartLevel" which matched a function in the PlayerHealth script. The video shows the GameOverManager script as responsible for restarting, so I changed things to use that approach.

In the Project view, go to Models -> Characters -> Player, and then in the Inspector's Animations tab, in Clips select "Death", expand the Events timeline, right click the tiny event marker and choose to delete it.

The GameOverManager script given in the project did not match the one in the video, but it's simple to add the missing lines.

Also make sure you check "Has Exit Time" in the state transition from "Empty State" to "Game Over Clip" on the HUD Canvas Animator. I'm not sure why, but that stopped the game over animation displaying as expected.

 

I had the same problem as you. I don't know why it doesn't work but after some trying out
I found a solution that will fix it.

The only thing you have to do is replacing

Code (CSharp):

1. if (Physics.Raycast(camRay, out floorHit, camRayLength, floorMask))

with

Code (CSharp):

1. if (Physics.Raycast(camRay, out floorHit, floorMask))

So you don't give the camRayLength to the the Raycast method. It is surely no proper
solution but it works fine

 

Just wanted to point out that if your enemy only moves to 0/0 you have to replace "FindGameObjectWithTag(...)" with "Find(...)" in your EnemyMovement class.
Find() uses the argument to find a game object with the same name (instead of looking for a tag), so it most likely is slower. If you really want to to fix this problem you should try to find a fix to use the tag.

I found this "Bug" using the latest unity version for osx yosemite and the latest asset version.

EDIT: Looks like uni00 already posted this, sry for reposting it. Found his post seconds after posting this.

 

I'm trying to add a script to a player object but I keep getting the message "please fix compile errors before creating new script components." Even after removing the script component off of the player object, it has a "parsing error" on the lower left hand screen. Any help please? Thanks.

 

I'm following the Survival Shooter tutorial. I'm on part 4 'Creating Enemy #1'. The NavMesh baking isn't coming out as it should. There are cracks and gaps in the floor. The enemy will not cross the larger gaps.

I have Unity 5.1.1 and Unity 5 Survival Shooter 1.1b.

I've used the settings changes from the Tutorial Upgrade Guide PDF, but still get these gaps between the floorboard edges.

Any ideas as to what is wrong here?

 

Hey! I am doing the Survival Shooter on Unity 5, and I was stuck on Harming Enemies. My gun fires, and the line renderer and lighting and everything works fine, but the line passes through the zombunny, or at least doesn't harm it. I don't know if this is the problem, but the Zombunny seems to be "not solid", the player can pass through it with a little resistance. These are the properties for Zombunny.



Also, this doesn't bother me a whole lot, but my slider works, its just that that it doesn't start all the way full, even though it says it is full.



Any ideas what to do? Thanks in advance!

 

I'm having this same problem, if you figure out what the solution is please message me sir!

 

I'm in the last phase, "Game Over". I created the animation (seemingly working) with all the elements for the HUD including canvas etc.

However the game starts by playing the animation, thus hindering me in playing the game since the view gets blocked out. I don't know what causes this, since the trigger should be set correctly in the animator controller. I made sure the "Has Exit Time" is unchecked in the AC. Other things that could be relevant to check?

 

I am having the exact same issue, my problem matches the screenshot perfectly. Any solution would be greatly appreciated.

EDIT: While it's not perfect, I got semi-decent results by increasing the voxel size. The holes around objects are a little big, but the mysterious holes in the middle of nowhere are gone.

My Settings:

Agent Radius: 0.75
Agent Height: 1.2
Max Slope: 45
Step Height: 0.34 (Unity warns about the max slope)

Drop Height: 0
Jump Distance: 0

Voxel Size: 0.28 - This required some tricky fine-tuning. Too big, and the nav mesh couldn't fit between objects. Too small, and the mysterious holes appeared. It still allows for a LOT of space around obstacles, so it's not quite ideal. But it should be good enough to finish the tutorial at least.

Min Region Area: 2

I think the moral of the story is to avoid having complex, bumpy, jagged floor meshes - it seems the navmesh system has trouble telling the difference between a crack in the floor and an impassible chasm. If you've got floor with bumps and creases and whatnot, use a shader to add the bumps instead of putting the bumps in the actual geometry to make the navmesh's job easier. Anyone with more experience can feel free to contradict me here!

 

Can someone please help me out!!!!!!!! I am up to part 7 and i finished it and when i went to play the zombunny wouldnt die what happens is that when i kill him the sound plays but the animation doesnt play and he keeps following me round and he can still hurt me. I found this error
NullReferenceException: Object reference not set to an instance of an object
PlayerHealth.Update () (at Assets/Scripts/Player/PlayerHealth.cs:38)
and when i double click it opens up the player health script and takes me to line 38 which is blank except for one of these }

 

THIS IS MY SCRIPT IF IT HELPS

using UnityEngine;
using UnityEngine.UI;
using System.Collections;

public class PlayerHealth : MonoBehaviour

public int startingHealth = 100; // The amount of health the player starts the game with.
public int currentHealth; // The current health the player has.

}


public void TakeDamage (int amount)
{
// Set the damaged flag so the screen will flash.
damaged = true;

// Reduce the current health by the damage amount.
currentHealth -= amount;

// Set the health bar's value to the current health.
healthSlider.value = currentHealth;

// Play the hurt sound effect.
playerAudio.Play ();

// If the player has lost all it's health and the death flag hasn't been set yet...
if(currentHealth <= 0 && !isDead)
{
// ... it should die.
Death ();
}
}


void Death ()
{
// Set the death flag so this function won't be called again.
isDead = true;

// Turn off any remaining shooting effects.
playerShooting.DisableEffects ();

// Tell the animator that the player is dead.
anim.SetTrigger ("Die");

// Set the audiosource to play the death clip and play it (this will stop the hurt sound from playing).
playerAudio.clip = deathClip;
playerAudio.Play ();

// Turn off the movement and shooting scripts.
playerMovement.enabled = false;
playerShooting.enabled = false;
}
}

 

So i finished the tutorial and i don'y know which one of the asset package files i got but i do have two problems
one is that its saying (
"SetDestination" can only be called on an active agent that has been placed on a NavMesh.
UnityEngine.NavMeshAgent:SetDestination(Vector3)
EnemyMovement:Update() (at Assets/Scripts/Enemy/EnemyMovement.cs:25)
)
but all my enemy's have NavMesh Agents on them so idk what to do

the second problem is that the Game Over animation doesn't even start when my player dies

 

NullReferenceException: Object reference not set to an instance of an object
EnemyAttack.Update () (at Assets/Scripts/Enemy/EnemyAttack.cs:57)
Can someone please help me with this error.

 

Hey guys, firstly I would like to say I am a junior programmer so it was cool that you guys focused on the engine rather than the code it's self.

Secondly, I seem to have this bug where i am actually able to pass through the floor objects, which then reveals another bug where the enemy can't find me. I can't lose! It's awesome right?



You can see I am in the middle of the toy there, the enemy can't find me. I have tried repeating part 1 of the tutorial again but I haven't had much joy. I am also able to walk off the edge of the map and keep going. What am I missing here?
